YOKOSUKA, Japan (March 28, 2011) Electric power dispatcher foreman A, Hideji Kawasaki, operates the supervisory control and data acquisition (SCADA) system to balance an electrical load inside the Commander Fleet Activities, Yokosuka SCADA control room. Members of the CFAY community are working to reduce the amount of power the base uses to help alleviate the electricity shortages after the nuclear reactors at Fukushima Daiichi power plants were damaged during the 2011 Tohoku earthquake and tsunami that hit northern Japan on March 11.

Trambus takes fire on test drive in central Turkey
MALATYA - 16.3.2015
A trambus which was on test drive in Turkish central province of Malatya caught on fire due to an unknown reason on Sunday, March 15, 2015.
Hopefully, no one was injured or killed in the incident since driver of the vehicle noticed the fire from camera and evacuated passengers, mostly students, before the fire spread.
The vehicle was totally destroyed after the incident. According to statement by Malatya Municipality, the reason of the fire will be determined after an inspection. - China News Agency
Malatya trambus fire inspection report:
The behaviour of the DC power supply seemed normal before and after the incident, as well as power surge regulator and transformers that supply the system. Scada and power levels also seemed fine (it's about software and computer systems probably.).
An independent German foundation (TÜV Thüringen) found a problem with the contactor box that could have caused an electric arc. An electric arc can be caused if the contactor box overheats and built up pressure inside the box could have caused the fire on 15.3.2015.
Conclusive report points out that the overheated contactor box is caused the accident, the same defect could not found on other trambuses.
Any kind of problems and defects on the trambuses are insured by the manufacturer, they started to build a new trambus. By 30.3.2015, damaged parts of the cables has been repaired and trambuses started new test drives. According to another sources, the faulty box was manufactured by Vossloh-Kiepe (Vossloh-Kiepe electric inlet box? or something like that)

www.trihedral.com – The integrated VTS Toolbox makes graphic display development easy by providing a wide variety of click & drag tools, a large graphics library and support for 3D graphics (developed in 3rd party packages).
Additionally, users can develop displays online and can test changes by switching between runtime and development modes without interrupting the application.
Gates at the London Ave. Canal Interim Control Structure began opening just after 8 a.m. today after the lake level subsided below 2.5 feet.
On Saturday, easterly winds and heavy rain caused Lake Pontchartrain’s water level to reach the operational trigger of 2.5 feet and rising, prompting us to close the gates and begin pumping.
Previous procedures called for closing the gates when the lake-side gage reached 4 feet and rising only during tropical events. Lowering that elevation and operating during nontropical events reduces the risk of exceeding the canal’s safe water elevation. It also maximizes the Sewerage and Water Board’s pumping ability during heavy rainfall.
A three person team had been located at the structure throughout the weekend and is responsible for operating the gates and pumps from the control room.
Supervisory Control and Data Acquisition (SCADA) equipment enables our emergency operations center to remotely monitor and operate the system as a redundancy in our operation plan, should the need arise.
The Corps’ pumps have a maximum combined capacity of 5,200 cubic feet per second at the London Ave. Canal.
The lake is currently at about 2 feet and we will continue to monitor rainfall and tides in the lake.
Molishus calls the OCC “the nerve center of the campus.” FRES staffers control and monitor utilities for the entire campus from the center through a sophisticated computerized Supervisory Control and Data Acquisition (SCADA) System.

This feeder that follows Nose Creek in a sensitive area is difficult to reach by vehicle. I'm sure this is one of the utility's more problematic feeders. A SCADA switch can be seen on the top of the hill in the background.
